I've been thinking about picking up a set of these, I've heard theyre awesome and how they're quick on target easy to establish and hold a good sight picture. I know that a set of sights won't make you magically a better shooter, I intend to train with them. I want a really good set of night sights for my defensive handgun (G19). What is everyone's opinion on them compared to meprolight, XS big dots, TruGlo, etc...? Also, on a side note, what is the difference/benefits between the different measuments on the height of the front sight? I think they come in measurements like .185, .200, .240 or something like that. Am I even asking the right question here? thanks guys!
